### Customizing the old values.yaml API

The new platform install API above deals with K8s level settings. The remaining values.yaml parameters deal with Istio
control plane operation rather than installation. For the time being, the operator just passes these through to the Helm
charts unmodified (but validated through a
[schema](pkg/apis/istio/v1alpha1/values_types.proto)). Values.yaml settings
